Be it known that I, GIEpIARD DOCK., of Wibonisco, in the-conn'ty-of-Daupllin,ond State of Pennsylvania,

have made and invented a new and useful Improvement in Railroad-Cnr Wheels; and I do hereby declare that' the following isa full, clem', and exhctndescription thereof, which will enoble those skilled inthe art to make and use the same, reference -being had to the aoconipunyingdra'wings, forming part of thisspeoicotion, in

Figure 1 represents a side view of a segmen'tnof n oor-wheel partly broken out at the huh to show my improved d'vioe for preventing the loss and wsste of oil, and v i i Figure -2 su enlarged Beotional'p'artinl view o( the same out through thc-line :v x, g. 1.

his invention relates to an improvement iu rni'lrnndnror truck-\vhoels,.i`or miningpdrposes, and consists- Y oil` in order to keep the axle constantly lubricated, 4whereby Athe weer and draught of the friction are greatly diminished, and the waste of oil is prevonted, thet"is cominon, especially with trucks or drift-cnrs for mining purposes. Y -On the inside of the hub A of the oar-wheel is `nn annular i recess, a, in .the bottom of which is a. small y,px-ejection, c, that rises 4nearly to the inner surface, hut terminating so that it shell not stony time come'in contact 4with the axle. A hole, e, is made through tho projection c for u feed-hole through .which to pour the 'oil into the recess a when the wheel lis turned in the propel-position.' It will h e seen-that hynxeans of' this arrangement the oil' put in the recess a cannot come out, hndwill remain to constantly lnbricate the axle. Having thus described my invention, I claim as new, and desire to securc b5" Letters Potenti -The perforatedprojeotion c, in combination with the recess a in the hub Aof a car-wheel, construc'tcdend A operotingsubstantially ns and for the-purpose herein described.
